The phytochemical screening of the root extract of Anthocleista djalonensis were carried out and indicated the presence of saponins, flavonoids, tannins, reducing sugar, steroids, phlobatanins, volatile oils and alkaloids which are active components present in the plant that makes it medicinal. 44.0 g of the powdered plant root extract using hexane gave a yield of 9.6 %, 39.77 g extract using methanol gave a 27.3 % yield, 28.9 g extracted using chloroform gave a yield of 11.2%. The thin layer chromatographic analyses carried out showed that two components separated from the hexane extract, two from chloroform extract, and one from methanol extract using the solvent mixture of ethanol/benzene/chloroform (1:1:3), ethanol/benzene (2:1), ethyl acetate/chloroform /petroleum ether (4:4:3). The anti microbial activity studies carried out showed that the plant extract is an antibacterial agent. It showed sensitivity towards disease causing organisms like Escherichia coli, Salmonella typhill and Staphylococci. This result reveals more on the the use of the plant Anthocleista djalonensis for herbal medicine.
Two sets of Organic dyes were developed using kassod and senna plant leaves. The first sets of dyes are the organic dye from the leaves of two plants while the second set is the dye produce after combining together the dyes from the kassod and senna plants leaves. The two sets of dyes were used to sensitize the grown films. The films were characterized and the current voltage values of the grown films were obtained. The solar simulation result of the grown film for Kassod dyed TiO 2 film was recorded for single dyes and for the combination of the two dyes. The result also covers absorbance of the spectra lines, absorbance coefficient values of the dyed TiO 2 , as well as transmittance and energy band gap values of the developed films. The precursors of tin (IV) chloride (SnCl 4 ) (60%) and hydrofluoric acid (40%) was deposited on the cleaned soda-lime glass using the chemical vapour deposition method and nitrogen gas was supplied as a carrier gas through the bubbler to form the FTO layer. Titanium dioxide paste (TiO 2 ) was deposited using a screen printing method to form M-TiO 2 .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
